The point on a plant where the graft is joined to the rootstock.
- ‘Next, locate long thin canes and canes that grow from below the graft union, if the plant is grafted.’
- ‘The graft union will usually form in six to eight weeks.’
- ‘You'll know a tree is on grafted rootstock if you see the graft union - a change in bark pattern or a ridge toward the base of the tree.’
- ‘To tell if your tree is grafted, look for the graft union - the spot where the two trees were joined - near its base.’
- ‘If the tree is grafted, position the inside of the curve of the graft union away from the afternoon sun.’
- ‘The bulge where the parts join, called the graft union, gets planted just at or below ground level, depending on your climate.’
- ‘Plant roses with the graft union 2 to 3 inches below the soil line in cold-winter climates, slightly above the soil level in warmer regions.’
- ‘Suckers are vigorous canes growing from the rootstock below the graft union on grafted roses.’
- ‘In cold winter areas the bud or graft union should be between one and two inches below the soil level.’
- ‘Plant the graft union, the bulge where the top joins the bottom, 2 to 6 inches below the soil line in cold-winter climates, slightly above the soil level in warmer regions.’
- ‘Plant the tree high, with the graft union above the soil line to avoid rot, in a well-draining, organically enriched, slightly acidic soil.’
- ‘Where winter temperatures drop to - 10F or colder, plant the graft union 4 to 6 inches deep.’
